FH3415D

XIN FEI HONG · MOSFETs · SOT-23-3L

FH3415D from XIN FEI HONG, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate; logic-level compatible, gate-source voltage limited to ±12 V with VGS(th) of -0.50 V min to -0.9 V typ at ID = -250µA.
2 S passive Source; continuous drain current ID = -6.5A (TJ = 150°C) and body diode forward current IS = -2.2 A.
3 D passive Drain; drain-source voltage VDS = -20 V maximum and pulsed drain current IDM = -26 A.
